RF Amplifier Circuit Design

I'm trying to design 3 RF amplifiers for 3 different frequencies. 1 Monolithic Amplifier and 2 Wideband Amplifiers, I currently have the signal source and its specifications. I am totally fine with buying modules as long as they are ready to be installed in the project (not prototyping boards). I need some kind of verification of design e.g. simulation, calculations or lab testing.
